3 Claims, (01. an -52.1)

This invention relates to improvements in window construction. 1

-One object of the invention is to provide a double hung window frame having a sill pivotally atached thereto which can be swung to one side whereby either sash can'be'lowered into a recess beneath the sill, to provide an opening between the two sashes through which the outside of the window can be washed by one from inside the building. When, for example, the inner sash has been lowered into the recess, a person standing on the inside of the building can reach through the opening between the sashes and wash the lower half of the outer sash and the upper half of the inner sash. The positions of the sashes can then'be reversed, that is, the inner sash can be raised to the upper part of the frame and the outer sash lowered into the recess and the lower half of the inner sash and the upper half of the outer sash can then be washed. This arrangement avoids the necessity of uncomfortably sitting or standing'onthe window ledge and getting wet or exposing himself to accident while washing double hung windows.

1 Another object of the invention is to provide a-window constructionwhereby the frame and movable sill can be assembled in the factory and placed as a unit in a building during its erection in the same manner that conventional window frames are installed at the present time.

A further object of the invention is to provide a frame and pivotally mounted sill construction which will be water tight andthus exclude rain, snow, etcgfromthe recess beneath the sill.

An additional object "of the improvements is to provide a double hung window, the sashes of whichea'n 'belocked together by a conventional sash lock and thereafter both sashes lowered the desired extent and locked in such lowered position to provide ventilating openings at the top and bottom of the window.

Other objects will be apparent from a consideration of the following specification and accompanying drawing, wherein:

Figure 1 is a broken perspective view showing thewindow frame and pivoted sill construction.

Figure2 is a vertical sectional view through an improved window construction.

Figure 3 is a fragmentary vertical sectional view showing the sill swung to outer position, and the innersash moved into the recess beneath the sill.

Figure 4 is a sectional view taken on line 4-4 of Figure 2.

Figure 5 is a horizontal section taken on line 5 5 of Figure 4'.

Figure 6 is a perspective view of one of the sill end plates or shields.

Figure 7 is a broken view partly in section taken on line 7"! of'Figure 2.. a

Figure 8 is a vertical section through one of the frame stiles and shields illustrating the modified construction of the latter} In the drawing, the frame of the window is indicated generally by the' numeral 10, and as shown in Figure 1, resembles the ordinary box type frame having frame stiles 11 having on their inner'surfaces the channels 12'and 13 for the upper and lower sashes, respectively. The frame is shown boxed in at its lower end beneath the sill 14. The stiles 11 are provided with openings 15 2.1, their lower ends through which the usual weights 10a are accessible when the sill-is in open position. I V

As shown 'inFigures 1, 2 and 3, the stiles 11 are provided with outer guide strips 16, and inner guidestrips 1'] as well as parting beads 18 which define the sash channels 12 and 13.

Secured to the outer surface of the frame is a sun-sill 19 to which the sill 14 is hinged or pivoted .as at 20. T

Attached to each" end of the sill 14 is a shield 21 shown in. perspective at Figure 6. These shields are preferably made of rustproof sheet metal and have arcuate inwardly turned flanges 22, each of which enters an arcuate groove 23 formed in the respectivestiles.

As shownat 24in Figure 4, the stiles are channeled out'to receive the shields or plates 21 so that their outer surfaces will be flush with the surfaces of therespective stiles. The shields alsohave flanges 25 at their forward edges which overlap the forward edges of the stiles, .as shown in Figure 1. A flange 26 on each shield is provided for attaching the shields to the ends of the sill. The shields also preferably are provided with strips 16a and 18a which are respectively continuations of the outer guide strip 16 and the parting bead 18,

By the arrangement described it will be seen that when a lower sash 2'? is raised the sill may be turned upon its pivots 20 to the position shown in Figure 3, at which position further outward movement is prevented by means of any suitable stop such as a plate 28 attached to the outer edge of the sill. During this outer movement the flange 22 of each shield will move within the respective arcuate groove 23 formed in the respective stile.

It will be noted that the flange 22 extends downwardly to approximately the lower edge of the member 14 as shown in Figure 6 so that the rear edge of the flange will remain in the groove 23 even when the member is moved to the position shown in Figure 3. The position of the flange 22 in the groove 23 prevents rain, dust, etc., from passing between the shields and the respective stiles and entering the recess 29 formed in the lower portion of the frame structure;

The flange 25 which overlies the forward edge of the stiles 11 also prevent rain from beating in between the stiles and the shields when the sill,

is in closed position.

The inner edge of the sill 14 preferably is provided with a sheet metal member 30 having a longitudinal roll or bead 31 as shown in Figure 2, which overlie the outer edge of the stool 32. This arrangement provides a tight construction,

as will be noted which in cooperation withthe shields 21 at the ends of the sills effectively excludes foreign matter from theirecess'29 when the sills are in closed.,position.-

In Figure 2 where the complete installation of the improved window'- frame is shown, having conventional trim therearound an'dthe sashes2'7 and 33 in position, it willbe seenthat the inner sash 27 may be raised in'the usual manner to permit the sill 14 to be swung outwardly'about the pivots to the position shown in Figure 3. The inner sash can then be moved into thereces's 29 which will preferably be about from 15 to20 inches deep. When'the sash has been lowered into the recess as shown in Figure 3, a space is provided between the two sashes through which a person standing on the inside of the building can reach for washing the lower portion of the outer sash and the upperportion of the inner sash. 1 mi The sashes can then be reversed; that is,. the inner sash can be raised to the upper part; of the frame and the outer sash moved into the recess 29 and the lower portion of the inner sash and the upper portion of the outer sash'can then be washed. It is thus unnecessary for aperson to sit or stand in the window ledge in washing the windows on the outside.

Another advantage of thepresent construction is that the window may be locked. by-means of an ordinary sash lock 34, after the sill has been moved to outer position, and the sashes then lowered as a unit the desired extent to provide a ventilating opening at the top.

The upper rail of the inner sash -may,preferably be provided with a latch bolt 35 shown in Figure 7, the bolt of whichmay be moved into one of several openings 36' formed in one of the stiles 11 of the frame, and the window thus locked in the'desired position. The air can circulate and pass through the opening at the top and also around the lower end of the lower sash as will be clear. The sill then being in the position shown in Figure 3 acts as a ventilator and prevents the direct entrance of rain or the like into the window opening.

In Figure 8 a modification ofthe shield is shown. .In this form the stiles '11- will have grooves. 3'7 formed therein in which a marginal bead 38 formed at the curved edge of the shield vis positioned. In other words the bead 38 may be substituted for the flange 22 of the preferred form. The modified shield will otherwise be as above described.

While I have shown and described certain embodiments of my invention for the purpose of illustration, I do not wish to be restricted specifically" thereto except as so limited by the appended claims. v I r 1 I claim: 1;A window construction comprising a double hung window frame having a sill and providing a recess beneath said sill, means pivotally securing said sill to said frame whereby the sill can be moved to uncover said recess foradmitting either of the sashes, said frame having-areuate grooves adjacent the ends of said sill, and members on the ends of said sill each having a 'lJOl't-IOH extending into one of said groovesto provide a water-excluding connection with said frame.
